one of the things that quantum mechanics reveals to us is that if we zoom in enough it turns out a dot or a particle does not always behave like this finite particle or a little ball of stuff instead it behaves as this washed out wave now if we take our daily world and zoom out to astronomical scales right where scales of of planetary systems turns...

Questions & Answers
Q: How does quantum mechanics describe the behavior of particles at different scales?
Quantum mechanics reveals that particles can exhibit either particlelike or wavelike behavior, depending on the scale. At microscopic scales, particles behave as waves and particles simultaneously, known as particlewave duality. On a macroscopic scale, they appear as particles.
Q: Why did the Newtonian worldview of physics fail at the microscopic scale?
Newton's laws of physics were successful in describing the macroscopic world but failed at the microscopic scale. At this scale, the behavior of particles, such as electrons and protons, is governed by Schrodinger's wave equation, which is more complex than Newton's laws.
Q: How does the application of Schrodinger's equation at macroscopic scales benefit scientific research?
The relevance of Schrodinger's equation at the largest scale allows scientists to utilize the solutions developed in quantum mechanics for understanding largescale structures in the universe. It provides a familiar mathematical framework for computer simulations and a deeper understanding of the macroscopic world.
Q: What are some unanswered questions concerning the scales below the quantum scale and above the macroscopic astronomical scale?
The relevance of quantum mechanics at both the smallest and largest scales raises questions about what lies below the quantum scale and beyond the macroscopic astronomical scale. Further exploration is needed to discover any interesting connections and understand the behavior of these unknown realms.
Summary & Key Takeaways

Quantum mechanics shows that particles can behave as washed out waves instead of finite particles, which is observed at both microscopic and macroscopic scales.

Newtonian physics, though successful in the macroscopic world, fails to explain the behavior of particles at the microscopic scale.

Schrodinger's wave equation governs the behavior of fundamental particles, and at large scales, it reproduces Newton's laws.
